there's even an angle with the gambia thing, regarding the struggle between the west and the chinese for control of resource extraction in africa, although the gambians seem to be playing both sides.
there's a link to a video in here somewhere where obama stands in front of a group of african emissaries and states, without blinking, that america does not intend to steal or extract resources from africa. it's perhaps one of the funniest things i've ever seen.
